Considerable amounts of starch granules can be present in the atmosphere from both natural and anthropogenic sources. The aim of this study is to investigate the variability and potential origin of starch granules in ambient air recorded at six cities situated in a region with dominantly agricultural land use. This is achieved by using a combination of laser spectroscopy bioaerosol measurements with 1 min temporal resolution, traditional volumetric Hirst type bioaerosol sampling and atmospheric modelling. The analysis of wind roses identified potential sources of airborne starch (i.e., cereal grain storage facilities) in the vicinity of all aerobiological stations analysed in this study. The analysis of the CALPUFF dispersion model confirmed that emission of dust from the location of storage towers situated about 2.5 km north of the aerobiological station in Novi Sad is a plausible source of high airborne concentrations of starch granules. This study is important for environmental health since it contributes body of knowledge about sources, emission, and dispersion of airborne starch, known to be involved in phenomena such as thunderstorm-triggered asthma. The presented approach integrates monitoring and modelling, and provides a roadmap for examining a variety of bioaerosols previously considered to be outside the scope of traditional aerobiological measurements.

大气中可能存在大量来自自然和人为来源的淀粉颗粒。本研究的目的是调查位于以农业用地为主的地区的六个城市记录的环境空气中淀粉颗粒的变异性和潜在来源。这是通过结合使用具有 1 分钟时间分辨率的激光光谱生物气溶胶测量、传统的体积赫斯特型生物气溶胶采样和大气建模来实现的。对风玫瑰的分析确定了本研究中分析的所有有氧生物站附近空气中淀粉的潜在来源（即谷物储存设施）。CALPUFF 扩散模型的分析证实，位于约 2 处的储存塔位置排放的粉尘。诺维萨德空气生物站以北 5 公里处可能是空气中高浓度淀粉颗粒的来源。这项研究对环境健康很重要，因为它提供了有关空气中淀粉的来源、排放和分散的知识体系，已知这些淀粉与雷暴引发的哮喘等现象有关。所提出的方法集成了监测和建模，并为检查以前被认为超出传统空气生物学测量范围的各种生物气溶胶提供了路线图。已知与雷暴引发的哮喘等现象有关。所提出的方法集成了监测和建模，并为检查以前被认为超出传统空气生物学测量范围的各种生物气溶胶提供了路线图。已知与雷暴引发的哮喘等现象有关。所提出的方法集成了监测和建模，并为检查以前被认为超出传统空气生物学测量范围的各种生物气溶胶提供了路线图。
